Patented Feb. 14, 1933 UNITED STATES THOMAS B. STEPHENSON, OF SPRINGFIELD, MASSACHUSETTS ASPIRATOR Application filed DecemberlS, 1930. Serial No. 503,530.

My invention relates to aspirators or inhalers of the type by means of which a quantity of liquid is vaporized for breathing through the nose or mouth.

It is an object of my invention to provide a small compact device of the character adapted to be carried in the pocket and constructed to prevent accidental escape of the liquid when not in use. Other and further objects will be apparent from the following specification and claims.

In the accompanying drawings which il lustrate one embodiment of my invention:

Fig. 1 is a side elevation showingthe dew vice with the cap in position;

Fig. 2 is a longitudinal section with the cap in position;

Fig. 3 is a side elevation with the cap removed;

Fig. 4 is a view similar to Fig. 3 but show ing the head in section;

Fig. 5 is an enlarged section on line 55 of Fig. 2;

Fig. 6 is an enlarged section on line 6-6 of Fig. 4;

Fig. 7 is an enlarged plan view with the head removed; I

Fig. 8 is a side elevation showing an alternative construction with the cap in position;

Fig. 9 is a longitudinal section showing the alternative construction with the cap in position;

Fig. 10 is a side elevation of the alternative construction with the cap removed;

Fig. 11 is a view similar to Fig. 10 but showing the head in section;

Fig. 12 is a sectional view of the head taken at right angles to the section of Fig. 11; and

Fig. 13 is a section substantially on line 13--13 of Fig. 10.

Referring to the drawings, 1 designates the liquid container, preferably made of glass. A ferrule 2 is threaded to the open end of the container at 3, the ferrule being exteriorly threaded at 5 to receive the closure member 6. Member 6 is in the form of a shell exteriorly threaded at 7 to engage complementary threads formed on the interior of the cylindrical cap 8. Member 6 carries pipes 9 and 10 and a pin 11 which are held firmly in the shell by a filling of solder or lead 12. A packing washer 4 is positioned between the ferrule 2 and filling 12. The inner end of pipe 9 opens adjacent the bottom of the container, while the inner opening of pipe 10 is 5 substantially flush with the filling 12.

The outer end of pipe 9 extends a short ways beyond member 6 while pipe 10 has a further extension and is provided on its outer end with an apertured button 13 and, intermediate the button and member 6, with a collar 15. An inhaler head 16 having a bore 17 is slidably mounted on pipe 10 between the button 13 and collar 15, the lower portion of the bore being enlarged to accommodate the collar 'and form a shoulder 18, between which and the collar is positioned a spring 19. Spring 19 tends to hold the head 16 against button 13 and the head is formed with a recess 20 to partially receive the button, as shown in Fig. 4, so as to give the head, when the parts are in this position, a smooth contour adapted for application to the nostril or mouth. The underside of head 16 is provided with opening 22 and 23 in which pipe 9 and pin 11 respectively engage. The purpose of pin 11 is to prevent rotation of head 16 about pipe 10. A transverse duct 25 connects opening 22 with the outside of the head, and, as shown in Fig. 4, the duct is so positioned that when head 16 is raised against button 13 a passage is formed through duct 25 and pipe 9 to the bottom of the container. A sealingplug of suitable material such as rubber or lead is positioned in the inner end of opening 22 to seal the end of pipe 9 when head 16 is forced downwardly against the action of spring 19. As shown in Fig. 2, the cap 8 is provided on the inside of its closed end with a cylindrical projection 27 having a diameter and length such that when the cap is screwed down on member 6 the edges of 1 the projection engage head 16 below button 13 to force the head downwardly against spring 19, closing pipe 9 as previously described. Pipe 10 is closed at the same time by engagement of the button 13 with a plug of lead, rubber or other suitable material 24 positioned in cylinder 27.

For convenience of manufacture and assembly, the end of cap 8 may be made as a separable member 28 threaded to the barrel of the cap as at 29. If desired, a clip 14 may be secured to the cap 8 to retain the device upright in the pocket.

In use, the container 1 is filled with a suitable liquid so as to bring the liquid level above the lower end of tube -9 yet leave a substantial space between the liquid and the closure.

10 The proper liquid level maybe indicated to the user by a ridge 30'formed on the container. parts consequently positioned as shown in Figs. 3 and 4, inhalation through the head-16 will draw air through duct 2, pipe 9 and throughthe liquid, the thus treated air then passing through pipe 10 to head 16. When not inuse, with cap 8 in position, the inlet and outlet pipes are tightly closed.

In Figs. 8 to 13, inclusive, I have shown an alternative structure. Referring V to these figures, 31 designates the liquid container preferably made of glass.

secured to the open end of the container, the

"ferrule being provided with exterior threads at 33 for engagement with complementary threads formed in a cap 34, and interiorly threaded at 35 to receive a threaded closure member 36. Secured in member 36 are pipes 37 and 38. The inner end of pipe 37 opens'adjacent'the bottom of the container and its'upper end'extends a short distance above the outer face of the closure member.

, The inner end of pipe 38opens to the interior ofthe container througha duct 40,while its upper end extends a substantial distance be-' yond the outer face of the closure member 36'. A sleeve 42'is slidably mounted on the outer end of pipe 38 and is provided on its outer end with an inhaling head 43. The opposite end of sleeve 42 is provided with a skirted flange 44 having an aperture at 45 through which a headed pin 46,carried by closure member 36, passes. Pin 46 prevents 7415i rotationof the sleeve 42 on pipe 38 and its head, by engagement with the upper face of flange 44, limits the outward movement of the sleeve on pipe 38. A recess 48 is formed M on the underside of the flange directly in line with the outer end of pipe 37. When flange 44 is moved adjacent the closure 36, the end of pipe37 enters recess 48 and the end of the pipe is tightly sealed by a packing48, made of hard rubber or the like, positioned in the I ,on the inside of its closed end with a cylindrical projection 52, having a diameter and With the cap 8 removed and the A ferrule 32 is part 57 threaded to the barrel of the cap at 58 and if desired a clip 55 may be secured to the cap 34 to retain the device in the pocket.

Means 56 to indicate the proper depth of liquid maybe molded or otherwise formed on the container. t
